Abstract
A bi-directional flyback circuit includes a primary side switch that regulates the re-circulated energy to achieve substantially zero voltage switching and a secondary-side switch that regulates the output voltage. No feedback circuit between an output side and an input side of the bi-directional flyback circuit is needed for regulating the output voltage.
Claims19
An electronic circuit, comprising:
- a dc-dc bi-directional flyback circuit which has a primary side switch that operates at zero voltage switching without a feedback circuit between an output side and an input side of the dc-dc bi-directional flyback circuit.
A method of controlling a dc-dc bi-directional flyback circuit, comprising:
- providing a primary side switch;
- and
- controlling said primary side switch to achieve substantially optimal circulating energy in the circuit, without providing feedback from a secondary side to a primary side of the circuit.
